Sock with Grip

ABSTRACT

A sock for helping to retain a pant leg in position on a leg of a wearer of the sock, includes a leg portion that extends along the leg of the wearer and over the pant leg, the leg portion having a grip on its inner surface for gripping the pant leg to resist upward movement of the pant leg along the leg of the wearer. The sock can also be used alone with the grip helping to reduce slippage of the sock on the wearer&#39;s leg. The sock also can help to maintain athletic equipment in place on the wearer&#39;s leg.

RELATED APPLICATIONS

This application claims the benefit of the filing date of U.S.Provisional Patent Applications Nos. 61/170,682 filed Apr. 20, 2009, and61/291,062 filed Dec. 30, 2009, the entire disclosures of which areincorporated by reference.

BACKGROUND OF THE INVENTION

Pants, such as jeans, are sometimes worn with boots, and with the lowerportion of the pant leg tucked inside the boot. The pant leg can easilyride up out of the boot, and can “bunch” above the top of the boot, inan unsightly fashion. It is, therefore, desirable to prevent this fromhappening—that is, to retain the pant leg inside the boot. Also, womenfind it frustrating when their socks or leg warmers slip down aroundtheir ankles. Socks or leg warmers (the term may be used interchangeablyherein) of the present invention will stick to the bare leg or to mostfabrics and ensure that the socks and leg warmers stay up at the desiredlength.

DETAILED DESCRIPTION

The present invention relates to devices for retaining a pant leg in aboot, and for keeping socks and leg warmers at the desired length, andfor keeping objects such as athletic equipment in place. Asrepresentative of the invention, FIG. 1 illustrates a retainer in theform of a sock 10 that is a first embodiment of the invention. The sock10 is adapted to used on a wearer's leg 12 to help retain a pant leg 14in position on the leg, inside a boot 16.

The sock 10 is configured as a leg warmer or sock that is worn over thewearer's foot 18 and that extends up the wearer's leg 12 for a distancethat depends on the length of the sock. The sock 10 has a foot portion22 that covers the foot 18 and a leg portion 24 that extends up the leg12. The leg portion 24 of the sock 10 is made from an elastic materialthat, when worn, exerts an inwardly directed force on the wearer's leg12. As a result, the leg portion 24 of the sock 10 can squeeze or clampthe pant leg 14 against the wearer's leg 12 to help prevent the pant legfrom riding up and bunching over the top of the boot 16.

In the embodiment of FIG. 1, the sock 10 is relatively short, andextends up the leg 12 only far enough to cover the ankle and thelowermost portion of the calf. In other embodiments, as discussed below,the leg portion 24 of the sock 10 is of a different length.

The sock 10 includes an adhesive grip 30 that is located on the innersurface 32 of the leg portion 24 of the sock. The grip 30 may be formedby deposition or printing of a flexible, permanently plasticizedmaterial 34, such as Plastisol, or a silicone resin, on the innersurface 32 of the leg portion 24 of the sock 10. The grip 30 could beformed as dots or letters 36 of material in a high density repeat logoprint as shown enlarged in FIG. 5, for example. The grip 30 preferablyextends 360 degrees circumferentially around the inner surface 32 of theleg portion 24 of the sock 10. The grip 30 may, alternatively, have adifferent overall configuration on the sock inner surface, such as instrips or other configurations extending vertically up the length of thesock.

If the grip 30 is formed as discrete elements, such as dots, the spacingof the dots on the inner surface of the sock can be random or in apattern. It may be preferable to provide a grip 30 that has a decorativeor logo pattern, as shown in FIG. 5. Functionally, it is only necessaryfor enough gripping material 34 be provided so as to satisfactorilyengage the pant leg 14, as described below, to prevent upward verticalmovement of the pant leg.

The gripping action arises partially because the pieces of grippingmaterial 34 are not flat on the inner surface 32 of the sock 10 butrather project inward and have surfaces 38 that extend transverse to theinner surface of the sock. This is shown in FIG. 6. The engagement ofthe pant leg 14 with the transverse surfaces 38 resists movement of thepant leg in a direction along the length of the leg portion 24 of thesock 10.

The gripping action also arises partially from the soft gripping surfacecharacteristics of the gripping material 34 itself. A gripping material34 is selected that has a higher coefficient of friction compared to thematerial of the sock 10 itself, so that it is more difficult for thepant leg 14 to slide along the gripping material and thereby slide alongthe sock.

In use, the wearer dons the pants and the sock 10. The leg portion 24 ofthe sock 10 is arranged to cover the lower end or hem of the pant leg14. The grip 30 that is on the inner surface 32 of the leg portion 24 ofthe sock 10 engages the pant leg 14.

The elasticity of the sock leg portion 24 helps to hold the pant leg 14inward on the leg 12. This force resists upward movement of the pant leg14 along the wearer's leg 12. In addition, the grip 30 abuttinglyengages the pant leg 14, and the friction between them resists movementof the pant leg along the wearer's leg 12. As a result, the pant leg 14is prevented from riding up on the wearer's leg 12, and from unsightlybunching over the top of a boot 16 that is being worn over the pant leg.

The grip 30 may extend over the entire leg portion 24 of the sock 10, asin the embodiment of FIG. 1. Alternatively, the grip 30 may extend foronly a portion of the length of the leg portion 24 of the sock 10. Theselected length of sock 10 to be worn depends on several factors. If thepant leg 14 extends quite far down the leg 12, as in FIG. 1, then arelatively short sock 10 can be used. If the pant leg 14 terminatesfarther up the leg 12, then a longer sock 10 might be appropriate, asshown for example in the embodiment of FIG. 2 wherein the sock is ofmedium length and extends farther up the calf past the ankle. In theembodiment of FIG. 3, the sock 10 is even longer, and extends evenfarther up the leg 12, to an over the calf position. In the embodimentof FIG. 4, the sock 10 is long enough so that the upper end of the sockcan be folded over the top of the boot 16. A longer sock 10 and longergrip 30 can provide more gripping force, as desired.

A sock of the present invention is not limited to use in the mannerdiscussed above. One example is the use of a sock such as the sock 10alone, as illustrated in FIG. 7. People often experience a problem withsocks staying up on the leg. This can be whether or not there is anassociated pant leg. With the sock 10, because it has the grip 30 on itsinner surface 32, the leg portion 24 of the sock will grip directly onthe bare leg 12 if there is no intervening pant leg 14. This will helpthe sock 10 to stay up on the leg 12, resisting downward movement of thesock on the leg. In this sense, then, the sock is usable alone, ratherthan to hold down a pant leg under a boot. The sock 10 is also better atstaying up against (inside of or outside of) leggings, tights,stockings, etc.

Also, a sock of the present invention can be useful in keeping athleticequipment in place over the leg, as illustrated in FIG. 8. For example,those participating in sports such as soccer, field hockey, skiing,golf, and ice hockey wear long socks as part of their athleticequipment. Providing a sock such as the sock 10 the sock with a grip 30as shown, on its inner surface, can help to maintain the sock (eitherupward or downward) in the desired position, either on top of orunderneath a piece of athletic equipment, such as a shin guard shownschematically at 40, for example. The gripping action of the sock canalso help to maintain a piece of athletic equipment in place over theleg.
